The rotary disk 15 is substantially a round board with a ring-shaped flange 21, which is designed to fit the round surface 36 of the seat hole 50 of the socket body 12; during assembling, the rotary disk 15 should be pressed so as to have the ring-shaped flange 21 passed through the fastening flange 39, and contacted closely with the round surface 36; i.e., the rotary disk 15 is limited to turn along the round surface 36 only. The outer surface of the rotary disk 15 is on the same level with the socket body. The center of the disk 15 has a round hole 22 and a rectangular hole 23 for receiving the power copper pin 26 to pass through; the power copper pin 26 has an angle plate 29 to be put in a recess 28 under the round hole 22; the angle plate 29 has a round hole to be aligned with the through round hole of the rotary disk 15 for receiving a hollow rivet 31, which is used for assembling the rotary disk 15, the power copper pin 26, the contact copper piece 32 and the wall surface 51 of the socket body 12 together as one unit. The power pin 26 and the contact copper piece 32 are connected together to fasten on the socket body 12 by means of a rivet 31 so as to have the power copper piece extended into the socket body 12.

The inner side of the rotary disk 15 has a through rectangular hole 24 and a recess surface 57; one side of the recess surface 57 has a curved positioning block 25. The rectangular hole 24 receives power copper pin 27; the contact plate 30 of the power copper pin 27 is attached flatly on the recess surface 57. After the rotary disk 15 is mounted in the seat hole 50 of the socket body 12, the contact plate 30 will be in contact with the round contact plate 53 of the ring-shaped copper piece 33; the power copper pin can extend into the socket body 12 via the stop plate 38 and the flat plate 52.

The seat hole 50 of the socket body 12 mounts the rotary disk 15, and the wall surface 51 of seat hole 50 has a through round hole 35; on one side of the round hole is a rectangular hole 41 receiving the contact copper piece 32 to plug into a fastening channel 58. The angle plate 55 of the contact copper piece 32 is attached flatly to the wall surface 51, and the center round hole of the angle plate 55 will be in alignment with the round hole 35 of the wall surface 51. When assembling, the contact copper piece 32 is mounted first in the rectangular hole 41 and the fastening channel 58; the power copper pin 26 and the rotary disk 15 have already assembled together; when the rotary disk 15 is mounted into the seat hole 50 of the socket body 12, the round hole 22 of the rotary disk 15, the round holes of the angle plate 29 and the angle plate 55 of the contact copper piece 32, and the round hole 35 of the seat hole 50 in the socket body 12 will be in alignment with one another so as to facilitate the hollow rivet 31 to pass through; after the hollow rivet 31 is riveted in place, the power copper pin 26 and the contact copper piece 32 will be fastened together to facilitate the rotary disk 15 to turn freely.

The wall surface 51 of the socket body 12 has another through rectangular hole 40, a guide channel 54 and a round channel 37; the rectangular hole 40 is used for receiving the flat plate 52 of the ring-shaped copper piece 33 to be plugged into a fastening channel 59 therein.
